Two days ago I coated a print here and when it came out only half the print was coated and the rest showed traces of coating only. I ran two normal cleans, all nozzles looks great on 5 of the channels except for the Yellow GO channel where almost all nozzles were gone, and on one of the light tone nozzles as well. I soaked the capping station with cleaning fluid mixed up with distilled water, and let it stand overnight, the day after I ran two cleaning cycles and a nozzle test and it had improved slightly, soaked it again, and let it stand overnight. Today I ran two cleaning cycles, and the nozzle check now shows nothing at all on the GO channel, and still pretty much crap only on that same other channel too.
Could this be a humidity problem? Low temperatures just hit us here, and we turned the heating on full for the first time this year?
I do need to change dampers and capping station on this machine anyway, but I have a feeling that this is not (only) the problem here, first time this happens…
All carts are almost full, the vent caps are open, and there seems to be fluid in the pipes as far as I can see visually…
Any ideas ?
